Application October 14, 1938, Serial No. 234,969

3 Claims.

My invention relates to improvements in an oil refiner, and it consists of the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide an oil refiner which is an improvement over the form of the invention shown in my patent, No. 2,064,097, issued December 15, 1936. In the patent, I show an oil refiner pack removably disposed in a casing. The casing in the patented device is in the shape of a sphere and is divided into two equal halves that are secured to each other by bolts.

In the present invention I provide a casing of two sections and provide cooperating threads in both sections so that the upper section may be screwed onto the lower one. One of the novel features of the invention is the manner of joining the two sections together so that an oil-tight seal is provided. The lower section is enlarged at its rim and the top of the enlargement constitutes a shoulder which carries one or more concentric ridges. The'outer periphery of the shoulder is threaded.

The cover or upper section of the casing has a cooperating shoulder provided with one or more concentric grooves. A flange encircles this shoulder and the inner periphery of the flange is threaded and is designed to receive the threaded portion in the lower section. The result is that when the upper section is screwed into position on the lower one, the ridges and grooves in the two shoulders will cooperate with each other and compress a gasket, disposed between the shoulders, to prevent any leakage of oil. This construction stops the oil from reaching the threads and therefore the casing will not leak even though the device is subjected to relatively high oil pressures.

In the two section casing, the bracket securing the upper section to the supporting surface may be freed from the section and swung about a hinge pin. This will permit the upper section to be removed from the lower section and a new oil refiner pack inserted, without the necessity of removing the casing from the support.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a part of this application,

' in which Figure 1 is a vertical section through the twosection casing, showing the oil refiner pack in elevation; and V Figure 2 is a top plan View of Figure 3.

In carrying out my invention, I provide a twosection casing comprising a lower section 34 and an upper section 35. The lower section 34' has a projection 2 that is internally threaded at 3. The casing receives an oil refiner pack indicated at 35 and the construction and operation of the pack is described and claimed in my copending application, Serial No. 234,968, filed October 14, 1938. The pack 36 has a threaded pipe 5' which is removably received in the threaded bore 3'. The projection 2 extends into the casing at 211. and carries integral pins 6 which engage with the string that is wrapped around the pack for preventing the pipe 5 from becoming accidentally unscrewed from the bore 3'. V

The section 34 has an enlargement 8' at its top and this enlargement has a shoulder 9' provided with two concentric ridges l5, see Figure 1. The outer periphery ll of the enlargement 8' is threaded and a rim i2 is provided at the base of the threads.

The upper section 35 has a shoulder I4 with concentric grooves 15'. A gasket [5' is placed between the shoulders. Thesection 35 has a flange l'l threaded for receiving thethreaded portion ll of the enlargement 8. The flange ll also carries a rim l9 that preferably encloses a portion of the rim I! when the section 35 is screwed into place. The concentric ridges [0 force the gasket I6 into the concentric grooves I5 and this makes an oil-tight seal for the casing.

The section 35 is provided with a projection 20' similar to the projection 2'. The projection 20' has a threaded bore 2| for receiving an oil inlet pipe 22'. The projection 20' has a portion 20a extending into the interior of the section and this portion lcarries pins 23' for engagingwith the top of the oil refiner pack 36 for preventing accidental rotation of the pack within the casing.

The upper section 35 has a cylindrical wall 35a that extends upwardly from the shoulder I4, The top 35b of the section 35 is provided with the projection 20" as already stated. Only one clamp 25' is used for the lower section 34, and this clamp has strips 25' secured together by bolts 26' and 21'. The strips have outwardly bent portions 28' which are slotted at 29' for re-,

ceiving screws, bolts or other fastening means for securing the section to a supporting surface (not shown). The bolts 26' and 21' may be tightened for causing the strips to grip the lower section. An upper clamp 3'! is pivoted to brackets 33 by a bolt 39. The brackets 38 together with the bent ends 28' of the clamp 25 secure the casing to the supporting surface.

When it is desired to remove the pack 36, it is merely necessary to loosen the bolt 40 that connects the free ends of the clamp 31 and then to swing this clamp up over the top of the section 35 about the bolt 39 as a pivot. The section 35 may now be unscrewed from the section 34 and then the new pack may be substituted for the used one. After this is accomplished, the upper section may again be screwed into place and then the clamp may be swung over the section and secured to the cylindrical portion 35a by tightening the bolt 46. In this simple way the pack can be renewed without removing the casing from the supporting surface.

In Figure 1 I have shown diagrammatically an internal combustion engine 30. A pipe 22' leads from the bottom of the engine crank case shown at 3| to the bore 21' and a return pipe 32 extends from the bore 3' to the crank case. In this way an oil circuit is established between the engine and the oil refiner.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

When the engine 3!! starts to operate, the oil pump, not shown, in the engine, will force oil through the pipe 22' and into the casing. This oil will then be forced through the oil refiner pack 36 in a manner disclosed in my co-pending application and will issue as refined oil from the pipe 5. The pipe communicates with the oil return pipe 32, that conveys the refined oil back to the crankcase.

Ihe projections 2' and 25 are preferably made non-circular in shape in order that wrenches may be applied to the projections, if necessary, in tightening the upper section in place or in removing it from the casing. The screw-type connection between the sections makes it possible to more quickly connect and disconnect them from each other than where the two parts are secured together by a plurality of bolts as shown in my patent. The casing may be provided with a drainage plug 33', if desired, and permit the draining of foreign matter that has found its way to the bottom of the casing.

While I have shown only the preferred forms of my invention, it should be understood that various changes or modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

I claim:

1. An oil refiner casing provided with an oil inlet and an oil outlet and having a lower section and an upper section removably secured to the lower section, a bracket for securing the lower section to a support, a clamp for gripping the upper section, means for pivotally securing the clamp to the support, said clamp being removable from the upper section and swingable about the supporting means for permitting the upper section to be removed from the lower section.

2. An oil refiner comprising a casing having an oil inlet, a lower section with an oil outlet in its bottom, an oil refiner pack having a pipe removably disposed in the outlet, means for securing the lower section to a support, said casing having an upper section threaded to the lower section, a clamp for gripping the upper section, a bracket pivotally secured to the clamp and being attached to the support, said clamp when freed from the upper section being swingable about the bracket into a position to permit the upper section to be unscrewed from the lower section, whereby the pack can be removed from the lower section without removing the lower section from the support.

3. In combination, a casing having a lower section and an upper section, the two sections being removably screwed together, the top of the lower section being enlarged to provide a wide rim and a shoulder adjacent the bottom of the threads on the lower section, a clamp made to be secured to a supporting surface and gripping the lower section beneath the shoulder, the latter resting on the clamp and preventing downward movement of the lower section in the clamp due to vibration or the like, a bracket arranged to be fastened to a supporting surface, a second clamp pivoted to the bracket and being swingable over the top of the upper section of the casing to grip the latter, the upper section having a wide shoulder cooperating with the rim of the lower section to form a liquid-tight seal between the two sections.
